4.0 Software porting questions
P.1 Are there any archive/FTP sites for AIX/RT software?
NOTE: I welcome information regarding ANY sites with RT software
for any OS on IBM RT processors. I am going to add a similar
section to each OS specific FAQ. Please send E-mail with
information and/or corrections.
Site: ftp-rt.graf.polymtl.ca
Anonymous ftp site for AIX-2.2.1 softwares: ftp-rt.graf.polymtl.ca
Fsp site (port 21) for AIX-2.2.1 softwares: fsp-rt.graf.polymtl.ca
Gopher site (port 70) for AIX-2.2.1 softwares: gopher.graf.polymtl.ca
Anonymous ftp access is NOT allowed from 9am to 6pm EST Monday to Friday.
Please respect these restrictions.
Fsp access is allowed anytime.

P.2 General "How to I port product " to AIX V2 ?
In general, I have not found a piece of PD software that I could not
make run correctly on AIX/RT, short of code that makes specific
dependencies on features either missing from the AIX kernel (such
as job control), or code that attempts to directly manipulate hardware
or assumes a particular hardware attachments or processor type.
Some programs that attempt to deal with kernel information or variables
can be difficult to impossible to port.
The AIX V2 system is at heart, a system V release 2 base, with
BSD 4.2 and some BSD 4.3 extensions mixed in, it also has some IBM
extensions and facilities by Interactive Systems, mixed in as well.
The standard C compiler is mostly K&R compliant with additional compiler
flags to support BSD portablity. There is *SOME* ANSI compliance in the
include libraries, but it is far from complete. No ANSI prototyping
is supported by the standard compiler.
The compiler shipped with AIX has its own standard setup, with
flags to make the include files SYSV compliant, and BSD compliant.
SYSV way:
cc -O -o foo.c
or
cc -DSYSV and/or -DUSG -O -o foo.c
Note: The supplied header files for AIX/RT do not test for the
SYSV or USG define, but a lot of public code does.
X11R5 has a -DUSGISH for a merged type system like AIX/RT.
BSD compatibility flags.
cc -DBSD -DBSD_INCLUDES -DBSD_REMAP_SIGNAL_TO_SIGVEC \
-O -o foo.c -lbsd
Note: There is another BSD flag: -DBSD_COMPILE_ONLY
This flag will cause additional defines and includes
that may produce a correct compile, but most likely will
NOT execute correctly, due to possibly incorrect interface
defines, or use AIX/RT unsupported system functions.
In addition to compiler difficulties, there are several unique changes
to AIX V2 for the IBM RT that can give problems.
The general most problem areas are:
- Differences in signal handling.
* AIX/RT uses SYSV style signal handling. To use BSD style
signals, add the -DBSD_REMAP_SIGNAL_TO_SIGVEC to your
compile options.
- Some missing library routines, most common are:
* strerrno, [ Others needed to be collected - MW ]
GNU software has some replacement routines with their code.
NOTE: If other routines are identified and coded, and you would
like to contribute your work, I hope to add any
contributions to the body of this part of the FAQ.
- Macro/include headers that may be different or missing.
* stdlib.h is missing, and usually not needed. If you have
some problems, add the following:
#include
* 'syslog.h' is located in
#ifdef AIX
#include
#else
#include
#endif
* Programs needing file locking need to use fcntl.
* File functions needing O_NDELAY, and O_RDWR flags will need
to include
- Macro heavy sources, like X11 will need to override the table
sizes in the compiler. See section S.12 on compiler flags that
can be helpful in this area.
- Missing commands, or commands with different flags.
* The most common problem is with grep and awk. This can
be fixed by replacing them with the GNU versions of these
tools.
See section S.12 for additional information and some specific flags for
the standard C compiler that can assist with compiling and porting
software to AIX/RT.
This list is incomplete... please feel free to send additions
on porting difficulties, missing system calls, bugs, ect..

P.3 BIND 4.8.3 (domain name server, and resolv libraries)
I have it ported and running, I will add it shortly to this FAQ. - MW
------------------------------
P.4 GDBM (Gnu DBM replacement)
I have it ported and running, I will add it shortly to this FAQ. - MW
------------------------------
P.5 IDA Sendmail 5.67b+IDA-1.5
I have it ported and running, I will add it shortly to this FAQ. - MW
------------------------------
P.6 ELM 2.3 PL11 or 2.4 PL20
I have it running. No porting was really necessary, just answer
the config questions correctly.
------------------------------
P.7 X11 R4 or R5.
Clients and libs are easy, mostly proper compile flags. I am working
on servers for R5, but it will take me a LONG while, sorry. - MW
------------------------------
P.8 GCC
I have the notes posted to the net, I just need to organize them
and add them to this section. - MW
------------------------------
P.9 inn 1.4
I have it ported and running, I will add it shortly to this FAQ. - MW
------------------------------
P.10 xv-2.1 (or xv-3.x)
I have it ported and running, I will add it shortly to this FAQ. - MW
------------------------------
P.11 Kermit

I have Kermit 5A(188) which was the latest when I did it. You
just unpack it and say either 'make sys3' for AIX 2.1 or 'make
rtaix' for AIX 2.2.1. I have 2.2.1 so I can't say how the sys3
option works.

P.12 Gopher 2.011
I have it ported and running, I will add it shortly to this FAQ. - MW
------------------------------
P.13 GNU fileutil-3.9
I have it ported and running, I will add it shortly to this FAQ. - MW
[I assmume that the FTP archive server now has my updated fix
that makes the 'df' command operate properly. - MW ]
------------------------------
P.14 others?

Posted around the first of each month to comp.sys.ibm.pc.rt, and
to comp.unix.aix.
This FAQ is dedicated to use of the AIX Version 2 operating system, running
on the IBM RISC processor known as the RT. The RT is known also as
an IBM model 6150 or 6151 machine.
